IPC: H04L29/08
Filed: 1989-10-11
Abstract: PURPOSE:To improve the transmission efficiency by setting a secondary station designation flag designating a secondary station receiving down-load data to an information field and varying a byte length of the secondary station designation flag in response to number of nodes (secondary stations). CONSTITUTION:Since secondary station designation flags 8a, 8b designating a secondary station receiving down-load data 9a, 9b simultaneously are added before the down-load data 9a, 9b sent from a primary station, each secondary station discriminates whether or not it processes down-load data 9a, 9b. Since 1st flags 7a, 7b representing the presence of the secondary station designation flags 8a, 8b are added before the secondary station designation flags 8a, 8b and the resulting data is sent, when a secondary station receiving data does not exist, it is sent by using the 1st flags 7a, 7b. Furthermore, since a 1st data representing the byte length of the secondary station designation flags 8a, 8b is added before the secondary station designation flags 8a, 8b and the result is sent, the byte length of the secondary station designation flags 8a, 8b is freely changed. Thus, the transmission efficiency is improved.

Title: Direct coupling clutch of hydraulic continuously variable transmission
Inventor: KOYAMA HIDEO
IPC: F16H61/4043
Filed: 1987-10-20
Abstract: PURPOSE:To minimize the operation lag without bringing a transmission impact by controlling the movement of a direct coupling clutch valve between the fully closed position and the directly connected position at a speed according to the engine output. CONSTITUTION:A controller 100 sets a target transmission ratio according to a car speed, at engine r.p.m, a throttle opening, etc., makes duty ratio control for solenoid valves 151 and 152, and controls the tranion of a hydraulic motor M via the primary and secondary servo valves 30 and 50. When the transmission ratio is detected to be zero, the direct coupling clutch valve DC is moved quickly to the fully closed position, and when a switch 58 detects that said valve DC reaches right before the specified opened position from the fully closed position, the duty ratio signal sent to the solenoid valves 151 and 152 is changed to modify the engine speed to a lower speed corresponding to the output of an engine E, whereby slowly moving the direct coupling clutch valve DC from the position right before the specified opened position to the fully closed position. So, the movement speed may be set as great as possible within the range where gear change shock can be restricted under the allowable level.

Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To utilize energy effectively and to reduce the consumption of fuel by preheating the air for burning by heat emitted from a burning part. SOLUTION: When an instrument is operated, a burning part 6 is heated to high temperature and the air for burning is heated to a higher temperature than environmental temperature outside an instrument case 10 collecting the heat emitted from the burning part 6 in the process of the air passing through an opening part 9, a surrounding part 7, a heat exchanger 4, a burning chamber 3 and a burner part 2, and supplied to the burner part 2. The temperature of the discharged mixed gas from the burner part 2 is raised by exhausted heat from the burning part 6.

Therefore, the effective energy transferred to the heat exchanger 4 is increased, thermal efficiency is improved, the energy is utilized effectively and the fuel consumption is reduced. In case of the same thermal efficiency, the heat conductive surface dimension of the heat exchanger 4 can be decreased and the instrument can be miniaturized and lighter.

Title: Power steering system
Inventor: SAKAMAKI MASAHIKO
IPC: B62D101/00
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a power steering system for improving the fuel efficiency while achieving excellent steering feeling. SOLUTION: First and second starting threshold values dθ1, dθ2 each representing the steering amount that varies until the motor is started are defined in accordance with the absolute angle θ in the stopped state of the motor. The first starting threshold value dθ1 is applied at the outward steering in the distal direction from the steering middle point θ0. The larger the absolute steering angle θ becomes, the smaller the first starting threshold dθ1 becomes. The second starting threshold value dθ2 is applied at the return steering toward the steering middle point θ0, which requires less steering aids owing to self aligning force. Therefore, the second starting threshold value dθ2 becomes larger as the absolute steering angle θbecomes larger.  The sum of the first and the second starting threshold values dθ1, dθ2 is set to the constant value '2A' irrespective of the absolute steering angle θ.

Abstract: PURPOSE:To get a metallic graphitic brush of low noise, high output, and long life by constituting it such that it has graphite, where the ingredients of ash are specified wt.% or less, and copper for its main ingredients, and that it contains specified wt.% or less metallic titanium. CONSTITUTION:A metallic graphitic brush has graphite, where the ingredients of ash is 0.1wt.% or less, and copper for its main ingredients, and contains 5wt.% or less metallic titanium. For the graphite, the one which is gotten by heat-treating the natural crystalline graphite at approximately 3000 deg.C using an achison furnace or the like and then, deliming it is used. It is to lessen the ripple on the performance plane of the brush as far as possible by specifying time ingredients of ash contained in the raw material small that we makes the quantity of ash 0.1wt.% or less. It is because the polishing property strengthens if it exceeds 5wt.%, and the abrasion of an armature increases, or impulse sound goes high that we have made the quantity of metallic titanium a maximum of 5wt.%. And the metallic graphitic brush is gotten by mixing copper powder with the powder of delimed graphite and metallic titanium, and molding and baking it.
